ATLANTA, Georgia (CNN) -- The first grandchild of Dr. Martin Luther King Jr. was born Sunday in Atlanta.

The girl, named Yolanda Renee King, is the daughter of Martin Luther King III and his wife, Arndrea Waters King, the family said in a statement.

The newborn weighed in at 7.5 pounds. Her birth comes two years and two days after her parents were married.

"We are excited about our precious gift from God and cannot express how fortunate we feel to have our beautiful baby girl. It is truly the happiest day of our lives. I know my parents are smiling down from heaven," the new father said in the statement released by Matlock Advertising and Public Relations, which works with the King family.

The girl carries the first name of her father's sister, the oldest of the four King children, who died last year.
